Question

I have a situation where I get a reference to an object that I would like to “overwrite” with another object of the same type. I know by design that the objects are of the same type. I do not have access to the parent object in this function.

The dataobject is defines as like:

    Class DataObject
    {
         public List<int> Stuff = new List<int>();
    }

Then there is a method

    void DoStuff(object obj)
    {
         // At this point I know that obj is List<int>
         // Create new object from some source
         var newList = new List<int>();

         // Here I would like to make the passed object the new object
         (the pointer of obj) = (the pointer of newlist)
    }

I don’t know if this is possible. It’s just something I’ve been banging my head against for a couple of hours now and my brain seems to have stopped working.

Thanks in advance

Answer 1

Pass object by reference:

void DoStuff(ref DataObject dataObject)
{
    dataObject = ...;
}

ref object won’t be allowed here, however.
